Thermohygrograph Chart Pad: 311
A year's supply of weekly charts in pad form, suitable for Sigma (by Sato) thermohygrographs set to measure -15 to 40 degrees C. Can also be used for Hismatsu or Kohari thermohygrographs. Humidity range of 0 to 100%. Pale orange coloured print. 307mm wide x 180 high, print area 292 x 180. If you have used our charts before, you will see in the bottom right hand corner 'Metco 311'; hopefully this makes it easy to re-order the right ones!
